After we were totally satisfied with our infant carrier of Romans we decided as a result of sitting for the Römer KING plus. This purchase proved far as total letdown. While there is the seat ansich to complain about little but the belt, especially the lock system is just plain cruel. Were the latch plates in the infant carrier of metal, one has to do it at KING Plus with cheap looking, smaller and fumeligeren plastic tabs. Could the Metallgurtzungen the infant carrier over a jetty together to "a" connecting part, which is then easily tucked into the belt buckle, this is no longer possible when King Plus. So threading the Kunststoffgurtzungen is a single fumbling in the lock. In poor visibility, as at night, almost impossible. If you have made it eventually comes when the ordeal tighten the harness on, which can only be achieved under a not unjustifiable effort. The straps should lt. Manual seat if you can hear a click. This click can be heard among us never. Since we have two equal seats and both have the same lack of properties, I infer from manufacturing defects. What good is a ansich class seat if was so saved the castle and the belt system, so that you would most like to regularly throw out of the car this garbage. For us, it has ausgerömert to this bad buy.
